WIND POWER
CARCOSEAL APPLICATIONS
WIND TURBINE COMPONENTS
CARCOSEAL APPLICATIONS
• Typical application :
• Main shaft bearing
• Rotor bearing
• Gearbox shaft
• Generator output shaft
• Blade pitch bearing
• Yaw bearing
•Typical Carco Products :
•Carcoseal/UN
•Carcoseal/UN/LA
•Carcoseal/SCA
•Customized rubber profiles
CARCOSEAL APPLICATIONS
CARCOSEAL FITTED MAINLY ON MAIN SHAFT BEARING:
-ENDLESS VERSION FOR NEW BUILD
VIRTUALLY NO REPLACEMENT FOR THE ENTIRE WIND TURBINE
LIFETIME (SPECIAL RUBBER COMPOUND RECOMMENDED FOR
BEST FRICTION AND OZONE RESISTANCE)
-SPLIT VERSION FOR RUNNING TURBINES
REDUCING TO A MINIMUM MAINTENANCE TIME TO REPLACE
OTHER OIL SEALS
“We want the customer to save money”
CARCOSEAL rotary shaft seals
• NO LEAKAGE OF BEARING LUBRICANT
• NO CONTAMINATION OF BEARING LUBRICANT
• LONGER BEARING LIFETIME
• SPLIT VERSION AVAILABLE, SHAFT REMOVAL NOT NEEDED
• DOWNTIME REDUCTION
• MANPOWER COST REDUCTION
• LESS OIL SEALS PURCHASED
• BIG SAVINGS IN MAINTENANCE !
CARCOSEAL rotary shaft seals
OTHER CLUES:
- OUR OIL SEALS ARE EASY TO FIT
- NO LEAKAGE THROUGH SEAL AND HOUSING
- NO HOUSING DAMAGE DURING SEAL FITTING
“We want the customer to save money”
Carcoseal Benefits Rubber formulated with PTFE
to reduce friction
“Carcoflon” PTFE surface
treatment:
• No stick slip effect;
• Lip protection during
dry running.
• Friction reduction.
Stainless steel spring keeping
lip homogeneously in
contact with shaft.
Large contact area:
• Guarantee against leakage;
• Less radial contact pressure;
• Less heat generation;
• Less shaft wear.
Oil/Grease

PTFE SHAFT
SEAL LIP
MENISCUS EFFECT
• Lubricant is pumped into the contact zone by the shaft rotation and provides a separating oil film, reducing friction and providing cooling. The reverse pumping effect keeps the lubricant contained in the contact band.
Carcoseal Split version - straight cut into full rubber for better sealing
- overlength on seal circumference to compress split
area and prevent leakage
- quick screwing of the stainless steel garter spring
- gluing on site not needed for applications with no
pressure
- easy and quick seal replacement
Dedicated rubber compound for
wind turbines: HT700
- Hydrogenated NBR with additives for longer working life.
- Wide working temperature range: -45° / +150°C
- Ozone resistant
- Characteristics and compatibility with the most used greases have
been verified by a third part laboratory.
- Fully in accordance with FAG specifications: S131319-1 “HNBR75
for seals in wind power turbine”
THE ORBITAL 2 PROJECT
CARCO WAS RECENTLY INVOLVED BY
AN ENGINEERING COMPANY INTO THE
SEAL DESIGN OF A NEW GEARBOX
FOR A 3 MW WIND TURBINE.
THE BIG GEARBOX IS CONNECTED
DIRECTLY TO THE ROTOR.
THE SHAFT DIAMETER IS mm 1750
AND 2 SEALS ARE DESIGNED TO KEEP
LUBRICANT INSIDE THE BIG BEARING
AND TO PREVENT LUBRICANT TO BE
CONTAMINATED BY DUST AND OTHER
POSSIBLE AGENTS.
CARCOSEAL/SCA/SPLIT FITTED BACK
TO BACK WAS RECOMMENDED.
SPLIT VERSION TO EASE SEAL
FITTING.
H-NBR COMPOUND TO GUARANTEE
THE LONGEST SEAL SERVICE LIFE.
PROBLEM SOLVING FROM CARCO
CARCO SPECIALISTS INSPECTED A 1,5 MW WIND TURBINE IN SPAIN.
WE DETECTED BIG GREASE LEAKAGE FROM MAIN SHAFT BEARINGS DUE
TO DEEP GROOVES ON THE SHAFT SLEEVE FROM ORIGINAL OIL SEALS:
TOO SOFT STEEL UNDER CHROMIUM COATING.
WE SUGGESTED TO MOVE THE SEAL INSIDE THE HOUSING WITH A
SPACER IN ORDER TO CHANGE THE CONTACT AREA ON THE SHAFT.
WE DELIVERED CARCOSEAL/UN/SPLIT WITH FULL SATISFACTION OF THE
CUSTOMER.
